The Sunpower photvoltaic cell is totally different and extraordinarily superior to a traditional photovoltaic cell. Thanks to the solid copper base, these solar cells are flexible and can provide extraordinary reliability and strength, enabling them to create panels that have won the world's energy efficiency record.

The design of Supower solar cells is also exceptional due to the fact that they are backcontact. This means that the connections are only on the back of the cell. This avoids seeing strips of connection to the surface of the cells, as is the case with standard solar cells:

Traditional photovoltaic cells lose power over time due to corrosion and damage. The exclusive design of SunPower cells eliminates most of the causes of malfunctioning of traditional cells. You will then be able to benefit from exceptional performance and savings.

Currently, these solar cells are the most efficient in the market up to 23%. This makes it extremely useful for applications in the nautical or aviation sector.

Even the famous Solar Impulse solar aircraft is powered by Sunpower solar cells with high efficiency such as those on our site:

Building panels is highly educational and fun, and are versatile as you can customize the voltage / current according to your needs, which is not possible with pre-assembled panels.

If you are new to the weapon and want more information about the cells and tips on how to make the welds and all the components you need, you can read our article in Learning ZONE which also explains it with a video, how to best match traditional cells .

We always add about 5% spare cells to compensate for breakages during welding or during transport, however, for any problem due to shipment please do not hesitate to contact us and we will do our best to solve any of your problems because 'It's important to us that you're 100% satisfied.
